Title:        Treatment of Styrene from Aqueous Solution by Coagulation / Flocculation Methods
Authors:   Arvind Kumar, Basheshwar Prasad
Abstract:  In the present study treatment of styrene and COD was carried out from synthetic aqueous solution of acrylonitrile butadiene styrene (ABS) resin wastewater using ferric sulphate and aluminum chloride as coagulants. The coagulation study was investigated with coagulant dosages (300-1500 mg/L) at different pH (4, 7 and 10). Optimum operating conditions for coagulation process viz. coagulant dosage and pH of the solution with a fix dosage of polyacryl- amide flocculent were estimated using jar test experiment. The results reveal that the maximum removal efficiency of styrene and COD were achieved 82.32% and 86.63% respectively by using ferric sulphate coagulant at optimum conditions (coagulant dosage 900 mg/L at pH 4). Removal efficiencies for styrene and COD were obtained 79.13% and 76.55% respectively at pH 7 and dosage 600 mg/L with aluminium chloride as coagulant.
